We're probably going to have a very simple app out by summer this year, but the emphasis will be on stuff you can't do in mobile mode. Eg notifications and PM inbox alerts that hook into the iOS push service, uploading images from the iPhone to your gallery, seeing your friends list easily, doing status updates that include pictures and geotagging, etc. We'll see how it fleshes out. To support this we're expanding the NeoAPI to include alot more things, so anyone could make iOS apps, Android widgets, etc.

My idea in this area is to enhance the experience with things only an app can do, and then tie it into the web mobile mode for a more seamless experience. Not sure if this is achievable, but for our limited resources, an app to reproduce what the mobile mode already does seems counter productive. One example of this for instance is Notifications that pop up in iOS, and when clicked on actually opens up the app with a list of Notifications and which ones are new, but clicking on the individual Notifications will open up the mobile mode page that triggered the Notification.

If you wish to follow the original suggestion, please keep tabs on this thread. That's also the place to discuss the app and post all your idea's of things you'd like to see in the future.
